STORAGE-BATTERY CELL.

Specification of Letters Patent.

Application filed March 10, 1916. vSerial No. 88,345.

. scription of the same. reference being had to theaccompanying drawings. and to the numerals of reference marked thereon, which form a partof this specification.

Storage cells used on motor'cars or other moving vehicles are subjected to extremely hard usage. and shocks and vibrations when transmitted to a storage cell tend to shorten the life thereof. This is due to the fact that a storage cell of the lead plate type with-the active material pressed into the grid plates is a more or less delicate construction pd slightdamage to the grid plates may result.

in irreparable injury to the cell.

This invention relates .to an improved batter cell construction wherein mechanical means is provided for positively interlocking the ,cell plates one. to another to resist relative movement thereof or chafing of the lates on the insulating separator mats pro- 'vided, so that, a substantially unitary and rigid combination of elements is afforded which is capable of resisting damag ng mechanical stresses imposed thereon.

. It is an object therefore of this invention to construct an accumulator cell wherein the elements of the construction are so designed as to.provide for the use of a 'novel inter locking and spacing means for the plates of the cell, so that the same are held as a rigid unit and vet thecell is easily assembled or.

dismantled when desired. 7

It is also an object ofthis invention to construct an accumulator cell \vherein'the plates are designed to coact with interlockmg m ans'which hold the plates properly associated with one another in rigid relation to prevent chafing of the parts andyet maintain the same in spaced insulated relation.

It is. also 'an important object of this invention to construct an accumulator cell wherein means are formed on the ends, and

- if desired centrally, of the respective plates 0f the cell to receive engaged therewith easily removable interlocking means which .co-act -yvith insulating elements to interlock the plates one to another in spacedinsulated relation and further acting to prevent buckling or warping of the plates at the points of support theieof.

It is furthermore an important object of this invention to construct an accumulator cell wherein theplates-of the cell are constructed to receive detachably connected thereon'insnlating lockin devices for locking the plates one to another in spaced relation. .co-act-ing with insulatingseparating means placed between the plates for the purpose.

It; is also an object of this invention to construct a simple and improved type of rigid plate accumulator cell constructed to afford easy assembly and dismantling of the cell.

The invention (in a preferred form) is Patented Dec. 23, 1919.

As shown in the drawings:

The cell plates are denoted respectively by the reference numerals l and 2, arranged in alternate spaced relation, and provided therebetween with insulating separator mats 3, of substantially the same area as the cell plates. .Each of said respect1ve cell plates --at the upper and lower portions. of the ends 3 and 4, in place of'two locking members 7 for this purpose slots 10,- are provided in thereof is extended and provided with a slot,

andthrough the registering slots ofgaid cellplates are inserted trapezoidal retaining plates 4, the ends of each of wh ch pro ect over the outer surfaces of the respect ve outer cell plates 1', as clearly shown'in liig. 6, held wedged therein by other trapezoidal or wedge shaped plates 5, driven into place after the plates 4, have been inserted into place. Inserted between the enlarged metal extensions of the respective cell plates are long 'upright insulator separator strips 6, which are provided with. slots at the upper and lower ends thereof adaptedto be disposed in register with the slots of the cell plates, so that the interlocking members 4 and 5, extend therethrough, as clearly shownin theisectional views of Figs-2 and 6.

' In the modified device illustrated in Figs.

4 and 5, I have shown three members comprising an upper trapezoidal bar or plate 7, notched and engaged with the ends of the slots in-the extensions of the'cell plates, and

asimilar lower notched member 8, with a wedge member 9, driven vtherebetween after said members 7 and-8, are in. place to hold the same rigidly in position.

The associated. plates 1 and 2, and separator mats 3, may also be rigidly lorkedto one another centrally thereof if so desired, and

each of the cell plates registering with similar slots in the separator mats 3, and inserted Y 1 thrdugh said registeringjslots is a notched slottedflfi "against t e ends of .the associated grid through notches 16, provided therefor in the end plate 13, andare adapted to receive insertedthrough theirapertures retaining pins 17, whereby the end plates 13, are held rigidly in place. 'The outer surface of the end plates 13, at the points ofcontact with the, pins 17, is grooved a slight amount so as to lock said end plates 13, from longitudinal movements.

. In 13 I have shown a slightly modified construction which is very similar to the construction shown in Figs. 1 and 2, withthe exception thatthe separator strips (5, are replaced by strips: 18, the upper and lower ends of' which at their inner edges are provided with inwardly projecting tongues orprojections 19, adaptedlto en-' gage. intornotches'cut in'the cornersof the separator mats V3 to thereby lock the same from movement. I f i In the construction illustrated in Figs.

1i and 15, I have shown separator mats 20, whichextend at each .end to the extreme ends offthe cell plates and are slotted in register therewlth to receive the locking members sand 5, therethrou b, so that'th' separator mats, as well ast e cell plates,

are locked from movement," so that the en tire construct on is rigidly and securely-- locked in assembled relation.-

The form ofinterlocking means shown in Figs'. 16 andfll', necessitates the formation on the ends :of the grid '-20,'and fitte lates of extended therebetween fiat plates 1 and 2,.and the separators 3, 1s a ladder shaped insulating plate 21. .Inserted through the slotted "lugs 20, and disposed over the 'exterior surface of the ladder shapeQpIate 21, is an insulating flat locking ba'rz'im'key 22, which may be tapered if so desircdto 'permit wedgin the same in engagement' with the slotte The operation of the various constructions vious from the description. The purpose in each case is to lock the assembly of cell plates and separator mats or insulating elements rigidly one to another substantially as a unit, so that no relative movement or chafing between the parts or warpin or buckling of the elements can take p ace, due to the shocks, vibrations and other effects due to severe usage, such as is imposed upon the cell when used on a motor car.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do' not purpose limiting the patent-granted otherwise than necessitated by the-@prizsr art.

I claim as my invention: M

class described comprising cell plates-haw lu s 20, to hold the spacing ladder plate in p ace.
